' uapplicationi December 4, 1941, SerialNo 421,662 .4 Claims ('Cl.- 19 7-186)- This invention relates/tel a hood for a typewriter, and its'general object "is to provide a hood that is primarily designedto protect the bearings'and other partsof the machine from eraser droppings which not only cause the parts to bind, but result in premature wear thereof, particularly due to the fact that the so-called typewriter erasers include abrasive material and the like.

A further object is to provide a hood that coversthe major portion of the top of the machine in advance ofjthe platen to protectfthe ribbon spools and associated elements from dirt and dust, and the hood includes flanges normally underlying the platen. to provide open end troughs for receiving the eraser droppings which can be readily removedfrom'the troughs by a brush or by blowing the same therefrom.

Another object is to provide a hood that is permanently secured to the typewriter by beinghingedlyconnected thereto, so that the hood can be swung to open position for ready access to the ribbon spools. i g p 3 A further object is to provide a hood that can be attached to a typewriter, with minimum change to the structure thereof.

This invention also consists in certain other features of construction and in the combinahereinafter fully described, illustrated in the accompanying drawing and specifically pointed the top wall and have straight lower edges ter of elongated formation to fit that "portion of the top'of the housing in advance'of the platen, so

as to cover the same and enclose thefribbon spools and associated parts for protection theref against dirt and dust.

The top wall is recessed "centrally from "the rear thereof, and disposed 'about the recess isa marginal depending flange 4, therecessbeing' of Q asizetogallowffor free movement of the'typebars and theflang'e being provided with round .ed notches 1 5" forpassage of the ribbon there through; as shown in Figurel. The recess'preferably increases" in width toward the front I thereof and thefront is preferably o'f arcuateg formation and merges into the sides in rounded v formation; as ibestshown in Figure f Formed 'ori'the'rearof the top wall i, upon op-* posite'sides of the recess and extending fromthe latter to the side wa1ls2, arerearwardly directed flanges 6 thatare downwardly curved from minating in a planeabove the lower edgesof the tion and arrangement of the several parts, to be out in the appended claims.

In describing the invention in detail, reference will be had tothe accompanying drawing wherein like characters denote like or' corresponding parts throughout the several views, and in which: 7 j

Figure 1 is a perspectiveview, illustrating my device attached to a typewriter and looking toward the front thereof. f V

Figure 2 is aperspective view of the hood per so, looking toward the rearthereof.

Figure 3 is a side view, illustrating. the hood in raised position in fulllines and in lowered or normal position in dotted lines.

Referringto the drawing in detail, .the letter A indicates the usual housingof a conventional typewriter, B the platenthereo'f and ,C a gage strip and card holder;

The hood is formed fromfsheet' metal or any, other suitable material to'provide aflat top wall I, side wallsZ, and a'front wall 3, the front and side walls merging into each other to provide rounded front corners to follow the shape of the housing, as shown in Figure 1-,and the hood is frontand side walls, forthe lower edges of the flanges 6 to underlie the forwardportion of the platen when the hood isin closed or normal poj sition, as shown in dotted lines in Figure 3, to provide with the platen whatmaybe termed troughs for receiving eraser droppings; The side, p walls 2 .at the rear ends thereof arecut away as; at I, from their juncture with the rear edges of the flanges .6- for disposal flush with the outer ends of, the latter, and such-allows the hood to snugly fit the top of the housing. v

The hood is permanently attachedto the typewriter by being hingedly connected tothecard I holder 0, and for that purpose; the cardholder has its end portions bent forwardly at right angles to provide tabs 8. .The marginal flange 4 extendsrearwardlyrfrorn the recessfor disposal beyond the inner edges of the flanges G to provide substantially triangular shaped ears 9 which together with the tabs 8 have holes therein through which pass rivet like pivot pins 10 for hingedly connecting the ears to the tabs, thus allowing the hood to be raised to its full: line position of Figure 3; so thatvready access can' be had tothe ribbon spools. v

When it'is desiredto make an erasure, the

carriage is shifted for-disposal of the typed mat-' ter to be-erased, above'one of the flanges 6, so that the eraser droppings will fall uponthe same,

' and the droppings can be removed fromrthe -flang'es 6 by a brush or byblowing'the same therefrom, it being obvious that the droppingsare brushed or blown toward the outer ends of the flanges for passage exteriorly of the machine,

thus preventing the droppings from coming in contact with the bearings, pivots and other parts of the machine to bind or cause premature wear thereof. V

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the o stru iiqnd inry h om n r,

tion and arrangement of the several parts; provided that. such changes fall within the scope of the appended claims; 3 e

What I claim is:

1. A hood for covering the upper portion of a typewriter in advance of the platen thereof, comprising a top wall and front and side walls, rearwardly extending flanges forrned on the top and side walls and being curved downwardly from the top wall to underlie the forward portion ofthe platen to provide troughs for. receiving eraser e pties and mar aritas 1 2 time to rh iipe fiiti s r o, a V
